Exhibit Page 27
submitted to the State Engineer, pursuant to SB 89-120 and SB 93-260. Based on discussions
with the Division of Water Resources, a formal substitute water supply plan will not be needed
as the Home Ditch water right will be used directly to make up any potential depletions of
ground water. Further, no augmentation plan will be necessary, as shown below.
Based on preliminary calculations, the Home Ditch appears to have adequate water rights to
substitute for water lost due to mining from the Dolores River alluvial aquifer and the water from
the Home Ditch water right is from that same source. If it is determined that there is
appropriation of water, any injury will be compensated for or corrected in accordance with
Water Court determination. During actual operations, the overall mining plan and layout of the
pit is designed to minimize water exposure to the atmosphere and thus keep evaporation losses
to a minimum.

Note: "Year 6" is the reclaimed state, with three ponds and no irrigation except of newly reclaimed areas.
Colorado soil management and conservation rules will be implemented to protect surface and
ground water quality and improve watershed management. As part of reclamation, as
conditions warrant, ponds shall be lined using backfill materials to meet the State Engineer
Guidelines for Lining Criteria for Gravel Pits. The ponds are not considered as water storage
after reclamation, therefore, all inflow of water into the ponds from any source, shall be
removed by draining to the Dolores River.
8. Prohibited actions necessary to protect water systems:
None. The riverside buffer zone (outside the permit boundary) is established for a variety of
reasons, including protection of possible small wetlands areas, preservation of an uninterrupted
floodway and floodplain, and prevention of downstream water degradation due to
sedimentation. The mining is planned to prevent negative impacts on ground and surface water
and to make maximum use of existing water resources in accordance with state water law.
9. Wetlands information:
US Department of Interior, National Wetlands Inventory Map, Boggy Draw Quadrangle, 1998,
identifies only two wetlands within 500 feet of the proposed permit boundary and none within
the permit area. The two identified are on the banks of the river and are classified as "Riverine,
Upper Perennial, Unconsolidated Shore, Temporarily flooded. No impact is anticipated.
s Based on 1.59 acre-feet per acre.
